Stryker M-SHORAD has 2.75 inch diameter Stingers and 7 inch diameter Hellfires. So this missile is planned to be used from the same missile launchers as Hellfires. Not that it needs to be 7 inch missile itself, just that it fits the same envelope. Being smaller all around makes this easy. They could've designed totally new missile with same diameter as Hellfire, but that would've been much more expensive than using Cuda technology and components.
